Touch display device, manufacturing method thereof and terminal equipment

Abstract

The invention relates to the technical field of display equipment, and discloses a touch display device and a manufacturing method thereof and terminal equipment, the touch display device comprises atouch display module, a middle frame and a glass cover plate; the touch display module comprises a display panel and a touch panel formed on the display panel. A touch flexible printed circuit board is bound on the touch panel, the touch flexible printed circuit board comprises a first binding part bound with the touch panel, a second binding part connected with the mainboard and a bending part bent along the edge of the display panel, and a plurality of through holes are formed in the bending part; a module mounting area is arranged on the middle frame, the touch display module is mounted onthe module mounting area, a frame glue structure is formed around the module mounting area, a preset safety distance is formed between the frame glue structure and the edge of the display panel, and the frame glue structure partially penetrates through the through hole; and the edge of the glass cover plate is bonded with the middle frame through a frame glue structure. According to the touch display device, the frame is effectively reduced, and a feasible technical scheme is provided for the full screen of the terminal.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a touch display device, a manufacturing method thereof, and a terminal device. Background technique [0002] At present, the AMOLED display device has been widely used in various electronic products as a display component of electronic equipment, and the AMOLED display module is an important component of the display device. Full screen has become the trend of display devices in recent years. In the application of full screen technology, a limiting factor is the lower frame. Currently, if figure 1 and figure 2 As shown, the touch sensor 02 (Touch sensor) of the AMOLED display module mainly adopts the form of an external touch panel (Touch). The flexible printed circuit board (T-FPC) 021 of the external touch panel (Touch) is separated from the flexible printed circuit board (M-FPC) 011 of the display panel 01, and the T-FPC needs to protrude from the frame of t...

Problems solved by technology

The glue on the lower frame directly avoids the T-FPC021 safety distance d 1 , so as not to cause the T-FPC to squeeze the display panel due to shrinkage of the glue, so the actual distance from the lower edge of the display module to the edge of the display panel is d 1 +d 2 , it can be seen that when the middle frame is attached to the AMOLED display module with an external touch panel, in order to ensure a sufficient safety distance, it is necessary to increase the lower border of the middle frame of the terminal product, which leads to the inability of the terminal to realize a true full-screen display.
